WRENCH.

`Application filed August 18, 1921. SerialNo.` 493,433.`

To all whom t may concern.'

Be it known that I, RUDOLPH L. GLABAZ- NYA, a citizen of the United States. and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful vImprovements in Wrenches, of which the following is a specificat-ion. i

My invention relates to new and useful improvements vin wrenches, and has for its principal object the provision of an improved construction of this character which vwill be highly eflicient in use.

A further object of my invention is the provision of a wrench of this character which can be conveniently manipulated inv close quarters for removing or replacing Anuts or bolts, and is especially serviceable inremoving or replacing nuts or bolts securing thel connecting rod of a crank shaft of an internal combustion engine.`

l A further object of my invention is the .provisionl of an adjustable bearing means whereby the socket member of the wrench can be readily adjusted into engagement withV the nuts or bolts to be removed or replaced. i

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The. invention will be best understood by reference l.to the accompanying drawings forming a part of this specification, and in Fig. 1 is a fragmentary side elevational View of an internal combustion engine partly ing, comprises a cylindrical sleeve or hous-v ing 10 having a cup-shaped support 11 integrally formed on one end thereof. Rigidly mounted on the support 11 is a housing 12 provided with an inner supporting flange 13 formed integrally therewith adjacent one end thereof and. adapted to support a chuck or socket member 14r rotatably ,mounted` thereon adapted to engage a nut or bolt 15 when.. 1n operative position. The inner wall of the socket member 14may be of any desired shape to accommodate the shape of the nut or `bolt to be operated on. The said socket member 14 is provided with an annular` ribv 16 and a central recess 17 for the reception of a hub 18 integrally formed on a bevel gear 19 seated against the annular rib 16 and rigidly secured to the socket mem-y ber 14 by anysuitable means. The periph- 4ery. ofthe bevel gear 19` projects beyond the annular rib 16 providing a recess 20 for the'reception of theflaiige 13. v Journalled 22 projecting into the interior of the housing 12, said projecting portion provided with a bevel gear y23 rigidly kfixed thereon and meshing with the bevel gear 19. The other in the cylindrical housing 10 is a crank shafty end of the ycrank shaft 22 is provided with j a handle ,24/ a1fordin'g meansfor stcadying the wrench in position. when the crank shaft I22 is manipulated.l Adjustably mounted on the` sleeve 10y is a collar24 rigidly secured in the desired position by means of a nutreceiving bolt 25. Pivotally carried bythe collar 24 is an angular lbent bearingmember 26 adapted to engage the edge 26of the opening 27 of the crank case 28 of'amotor,

as best shown in Fig. 1. By this arrange4r Ament of a bear-ing memberthe socket mem-f ber 14 can be readily adjusted into engagement with the nut or bolt 15. The object of pivotally connectiiigthe bearing; members ofthe sleeve 10, when required, .so ,as to 4bring the lsocket member.14` Vinto operative engagement with the nut 15 which is to be removed.y l f In operation v,the bearing `plate 26 is brought into engagement V.with the edge 26 of the opening of the crank case 28, andthe sleeve-10 is adjusted in thedesired position,

. bringing the socket member 14 into engagement with the nut or bolt of the connecting rod to be removed or replaced. The bearing member 26 is held in posit-ion by means of the handle 24,and by rotating the crank shaft 22, the socket member 14 is caused to rotate and thereby accomplish its respective duty, as can be readily understood.

While I haveillustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modificationwithout departv26 t0 the collar 24 is to permit oscillation,

ing from the spirit of the invention. l, therefore, do not Wish to be limited to the precise details of the construction set forth, but desire to avail myself of such variations and modications as come Within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure byLetters Patent, is

l. A Wrench of the class described comprising a sleeve; a nut receiving socket mounted on said sleeve; an operating shaft journalled through said sleeve and operatively connected to said socket; an angular bearing memberl adjustably carried yby said sleeve adapted to engage the edge of the opening of a crank shaft casing, substantially as described.

2. A device of the class described comprising a sleeve, an angular formedbearing member on said sleeve adaptedto engage the edge of the opening of a crank 4shaft casing of a motor; a support formed on one end of said sleeve; a socket member rotatably mounted on said support; an operating shaft journalled in said sleeve; and means mounted on one end of said shaft engaging said socket member for rotating said member, substantially as described.

3. A Wrench of the class described coml prisinga sleeve; a nut receivingsocket c'arried by said sleeve; an operatingshaft journalled through said sleeve and operatively connected to said socket; and an angular bent bearing member carried by said sleeve adapted to engage the edge of the opening of a crank shaft casing, substantiallyr as described. Y

4C. A device of the class described comprising a sleeve; a support formed on said sleeve; a housing having an inner annular iange mounted on said support; a socket member rotatably supported by said flange; an annular rib formed on said socket member; a bevel gear rigidly liXed to said socket member, the periphery of said gear projectingbeyond said rib forming a recess for the reception of said ange; an operating shaft journalled in said sleeve; and a bevel gear mounted on said shaft meshing'With said rst mentioned gear for rotating said socket member, substantially as described.

5; A device of the class described comprisingV a sleeve; a support formed on said sleeve; a housing having an inner annular flange mounted on said support; a socket member rotatably supported by said flange; an annular rib formed on said socket member; a bevel gear rigidly iXed to said socket member, the periphery of said gear projecting beyond said rib forming a recess for the reception of said flange; an operating shaft journalled in said sleeve; a bevelgear mounted onI said shaft meshing With said first mentioned gear for rotating said socket member; and a bearing member pivotally mounted on said sleeve adapted to be adjusted longitudinally, with respect thereto, substantially asv described.

6. ln a Wrench, the combination with `a sleeve; of a nut receiving socket member carried by said sleeve;`an operating shaft journalled in said sleeve and loperatively connected to said socket member; and a bearing member pivotally carried by said sleeve to permit lateral oscillation of said sleeve with respect to said bearing member,

substantially kas described.

7. in a Wrench, the` combination With a sleever` of a nut receiving socket :member carried by said sleeve; a shaft )ourn'alled' 1n said sleeve and operatively connected to said" socket member; andan angular shaped bearing member pivotally carried by saidsleeve adapted to 'be adjusted longitudinally with respect thereto and to permit: lateraloscillation of said sleeve With respect to said bearing member; substantially as described.

8. ln a Wrench, the combination With a sleeve, of a socket member c arriedfby said sleeve adapted to make operative engagement with a nut of the connecting rod ofa crank shaft; and a bearing member pivotally carried by said sleeve adapted totengage the edge of the opening of a crank shaft casing and to permit lateral oscillation of 'said sleeve with respect to said bearing member,

substantially as described.'
